Linwood’s center stands about 1,340 ft above sea level. Within three miles the land runs from 1,300 ft to 1,610 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Indian Hill, about 1,510 ft, 1 miles south-southwest.
Under the town center the state geologic map shows Dakota Group (sandstone, shale), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 16 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Linwood reaches the Gulf of America by way of Skull Creek, the Platte, the Missouri and the Mississippi: about 1,840 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Linwood; river miles along the main stem, rounded.
